Tips
• If
•
•
for Sweeping
ground speed is too fast, debris will pile up in front
of the broom, causing it to bulldoze instead of sweep.
This can damage the broom.
More pressure will not give a better sweep, but it will
wear out the broom faster
A level broom lasts longer
.
.

•
When sweeping, try to keep the flange on the top of
the pivot pin level with the gage plate
(Fig. 13). This will allow you adequate room for
movement if you run over bumps or low areas.

Servicing
When

a Castor Wheel
that the wheel bearings are worn. Perform this procedure
to fix a wobbly castor wheel.
1.
Start the engine and raise the broom to highest
possible position.
2.
Install the cylinder locks then stop the engine.
3.
Remove locknut and capscrew that secure the castor
wheel assembly in the castor fork
(Fig. 24).
4.
Remove the castor wheel from the fork (Fig. 24).
5.
Remove the outer bearing from wheel hub and allow
the bearing spacer to fall out (Fig. 24).
